Independent breeding of arborvitae in the local area is not a difficult and very exciting event. However, it is necessary not only to propagate correctly, but also to correctly plant the conifer.
Advantages of thuja autumn propagation by cuttings
The main advantage of the reproduction of conifers in the autumn is the ability to obtain a full plant in three years. Such a plant will fully comply with the botanical characteristics of the maternal culture, but the survival rate is not at a high level.
It should be noted that cuttings grown at home are quite difficult to tolerate the transplantation process, they have not too high resistance to the pathogenic flora and sharp temperature drops. However, it is autumn propagation that is most often practiced by gardeners and florists in our country.
When and how to properly handle thuja in the fall
Cutting of planting material is carried out only from branches that have reached the age of two and are well developed. When slicing, you need to remember that the shoot should be about a quarter meter long. The best option is not cutting the cuttings with a pruner or knife, but breaking off from the branch of the mother plant, which will allow you to get planting material with a characteristic “heel” from the bark.
All harvested conifers cuttings must be placed for several hours in a container filled with water with the addition of a growth stimulator and bio-root. The main process of germination of cuttings, it is advisable to carry out inside a special greenhouse, which must first be filled with clean river sand, peat crumb and soddy soil, mixed in the same proportions.
Thuya reproduction methods
It is important to remember that a nutritious soil mixture must be sanitized before filling, using a sufficiently strong solution of potassium permanganate for this purpose.
Cuttings prepared and pretreated in growth stimulants should be planted in a moistened nutrient substrate, keeping a distance of 50-70 mm. The penetration into the nutrient substrate should be approximately 20 mm. Landings in the greenhouse must be covered with a transparent plastic wrapthat will allow pritenit rooting cuttings of the conifer from direct sunlight.
Why you can not store thuja cuttings
Cuttings can be performed in spring or autumn, but such planting material is not subject to storage, since extremely rapid dehydration and death of wood occurs. Such a vegetative method, in comparison with seed propagation, is the most convenient in conditions of indoor and home gardening.
Cuttings from spring or autumn harvesting require proper rearing. For this purpose, it is necessary to form special ridges, which are called the "school". Under such conditions, planting material will remain for a couple of years, after which the conifer seedling is transplanted to a permanent place. The planting material cut in the autumn period is planted on the ridges of the school only next year.
The technology of rooting thuja cuttings at home in the fall
At home, rooting of the conifers for autumn propagation is most often performed using peat moss sphagnum. It is also necessary to prepare a plastic film, a clean cloth and a growth stimulator, including Epin or Kornevin. The technology of this method of rooting conifers at home is not complicated, but necessarily carried out taking into account the following recommendations:
- place thuja shoots in a container filled with water with the addition of any root stimulant for about twelve hours;
- moss-sphagnum pour boiled warm water for about three hours, which will allow the natural material to increase in size, as well as well absorbed by moisture;
- spread a wide fabric strip on a flat surface, visually divide the strip width in half, and evenly distribute the moistened sphagnum moss evenly over the entire upper part;
- with an insignificant distance from each other, it is necessary to lay the chopped cuttings of the conifer, and then cover them with moist sphagnum.
At the final stage, it is necessary to cover the cuttings with the lower part of the fabric strip, and roll them into a not too dense roll, which is placed in polyethylene. The blank must be placed in a room with adequate natural light. If necessary, the moss should be periodically moistened with clean water at room temperature from a household spray.
How to cut a thuja
What you need to know about planting thuja cuttings in the fall in the open ground
Thuja is a photophilous plant, and in shady areas such an conifer can quickly lose its natural splendor and all its decorative appeal. The site should be represented by fertile and well-permeable soils. with enough moisture. Before starting planting a coniferous plant, you need to prepare a good planting pit, the dimensions of which depend on the parameters of the development of the roots of the culture. A drainage layer in the form of broken brick or expanded clay is poured at the bottom of the landing pit. A nutrient substrate based on sand, peat and garden soil is filled up from above.
The ideal time for planting is September and early October, but always before the appearance of sufficiently strong and stable frosts. The roots of the plant should have time to take root before the onset of winter. The root neck of a coniferous plant when planting should be placed on the same level with the ground.
After planting, watering is performed, and timely and proper top dressing will allow the plant to take root well and easily bear the stress caused by planting. As an autumn top dressing, you can use potash and phosphorus fertilizers. After planting, you need to provide a decorative culture with daily irrigation activities and the usual sprinkling with a hose.
Subject to the planting regime and care rules, you can count on getting a beautiful and strong coniferous plant.
